Abstract:

High-resolution solid-state N.M.R. studies of dilute spins are now possible using cross-polarisation and MAS techniques. A systematic evaluation has been undertaken to determine their applicability to spin-½ metal nuclei, in particular (^195)Pt and (^119)Sn. In addition, an extensive (^13)C and (^31)p solid-state N.M.R. study has been carried out on a selection of Pt(II) complexes, supplying information on isotropic (scalar) coupling constants and shielding anisotropy. The majority of (^119)Sn and (^195)Pt spectra exhibit a multitude of spinning sidebands due to the large shielding anisotropy

Neste trabalho foi investigada a eletrooxidação de etanol sobre eletrodos nanoparticulados binários Pt-M1 (M1 = Sn ou Re) e ternários Pt-M1-M2 (M1 e M2 = Sn e Re) suportados em carbono. Estes materiais foram preparados pelo método da redução por álcool e foram caracterizados por difração de raios-X e microscopia eletrônica de varredura associada a EDX. Os eletrodos foram montados utilizando-se a técnica de camada ultrafina. Os resultados eletroquímicos mostraram que a adição dos diferentes metais à platina aumentou a atividade catalítica tanto dos eletrodos binários quanto dos ternários. Os

Abstract:

Sistemas de células a combustível alimentadas por etanol (DEFC - Direct Ethanol Fuel Cell) são vistos como candidatos para ajudar preencher a lacuna entre a demanda e oferta de energia elétrica. Entretanto, as DEFC ainda não apresentam desempenho tão elevado, que incentivem a comercialização. Um dos principais esforços para elevar o desempenho é obter catalisadores anódicos mais eletroativos e estáveis para reação de oxidação de etanol (ROE). Neste trabalho, visou-se obter e avaliar catalisadores Pt-Sn-Terras raras (La, Ce, Pr e Eu) para ROE. Os catalisadores foram sintetizados a partir de alg

Abstract:

The International Temperature Scale of 1990 (ITS-90) defines the present S.I.(“System International”) means of measuring temperature. The ITS-90 uses the freezing points of metals to define temperature fixed points. It also uses long-stemplatinum resistance thermometers to interpolate between the fixed points from 660 °Cdown to 84 K (if one includes the Argon triple point). Impurities are a major source of uncertainty in the fixed point temperature (of the order of 1 mK). And a better understanding of the impurity effect is required to improve top-level metrologicalthermometry. Most historical

It was found that supported platinum reacted with oxygen when calcined at high temperatures to form PtO2 and sublimates as PtO2 (g).

However, several ITO film properties need to be improved for organic light-emitting diode (OLED) applications, such as the ITO surface work function and roughness. Our previous study have demonstrated that by doping nickel (Ni) into ITO film the characteristics of OLED devices can be largely improved. This is because Ni or NiOx appears at ITO/Organics interface, give a higher work function (> 5.0 eV) than that

Abstract:

<p>Due to the feasibility of ethanol production in the United States, ethanol has become more attractive as a fuel source and a possible energy carrier within the hydrogen economy. Ethanol can be stored easily in liquid form, and can be internally pre-formed prior to usage in low temperature (200C – 400C) solid acid and polymer electrolyte membrane fuel cells. However, complete electrochemical oxidation of ethanol remains a challenge. Prior research of ethanol reforming at high temperatures (> 400C) has identified several metallic and oxide-based catalyst systems that improve ethanol conver
